壁面吸着分解モデルとモデルパラメータ同定: 過酸化水素H_2O_2の室内濃度分布予測と除染効果のモデル化 第1報

摘要

Effective decontamination is essential and critical if indoor spaces are contaminated by various kinds of biological contaminants especially in hospital and health care facilities. Dissemination of vapor hydrogen peroxide is one of the effective ways to decontaminate biological contaminants in indoors. This study used computational fluid dynamics (CFD) method as a prediction tool for non-uniform distribution of vapor hydrogen peroxide in indoors and also the deposition/ decomposition on wall surfaces. Here, CFD model incorporating reactive transport of vapor hydrogen peroxide was developed and sensitivity analyses were carried out to estimate surface concentration of vaporized hydrogen peroxide and de-contamination efficiency.%各種の建築空間や車両，航空機客室内といった閉鎖空間内では，室内環境維持のために，適正な換気量確保と汚染物質発生量の最小化が必要とされる.汚染源制御と換気量制御の2点が空気質制御の基本であるが，特に高度の空気清浄度が要求される空間，例えばクリーンルームや病院においては，効率的な化学物質除去や，除菌·滅菌·殺菌技術の開発に関する需要が高く，現時点までに様々な手法が提案され実用化されている.
